Ouch, yes, I've seen this one before. It's a terrible page, but it does demonstrate a rather interesting optical illusion: if one stares at the black text, it appears to move up and down in time with the background.

The terrible "You are possibly not secure in your own personal faith" warning message made me laugh, anyway.

In FF, it was just that for me. However, after a bit, in Opera the background became fixed except for a few bands of it that were still undulating and then there this dove flapping its wings in time to music and wandering around the page (sometimes in a backward direction, sometimes getting sort of stuck in a certain area) trailing behind it a bit of the multicolored background emanating from a box of said background around the dove and making the smaller text and links even more difficult to read in its wake.

Argh, yes. Here's what it looks like, for the faint of heart or epileptic of disposition.

An Opera bug, perhaps? Not one one would hope to encounter every day, of course, but perhaps it bears reporting anyway.
